Description

[Detailed description of the invention] This invention relates to simple scissors for cutting paper, cloth, synthetic resin films, and other sheet-like objects, and in particular takes advantage of the springiness of the metal plate to make it easy for anyone to cut. In addition to making it possible to open and close the metal plate, by using the cut edge engraved on the metal plate as the cutting edge, it is possible to reliably cut the target object without the need for special cutting edge processing, and it is also inexpensive as a product. It is designed to provide security for mobile devices.

Hereinafter, the structure of the present invention will be specifically explained based on the illustrated embodiments. In FIGS. 1 to 7, A is a quench-hardened thin steel plate or other metal plate having spring properties, and 1 is its outline. This is a cut line of a predetermined length that is carved in the center of the shape (a rectangle with rounded corners in the figure) at the same time as punching out the shape (a rectangle with rounded corners in the figure). The cut edge is determined so that it becomes the cutting edge C of the product-scissors as it is.

In that case, as is clear from the enlarged view of Figure 7, the cut line 1
is carved at a non-perpendicular angle α with respect to the plate surface (plane) of the metal plate A, so that the ridge line of the cut edge rubs against each other as a sharp cutting edge C.

However, when viewed from the plane of the metal plate A, the cut line 1 is not limited to a straight line as shown in the figure, but can also be formed into a sawtooth shape, a circular arc shape, or other forms, for example.

Reference numeral 3 denotes a bending guide hole which is punched out in the part following the engraving of the cut line 1, and 4 is a bending guide hole which is also punched out in each half 2 of the metal plate A, facing the position near the engraving of the cut line 1. A plurality of lever mounting holes 5 are a pair of left and right bending lines provided on the plate surface of the metal plate A so as to intersect with the cut line 1 at an acute angle β, and each half 2 of the metal plate A The cutting edge C is bent in an upright shape from the folding line 5 in opposite directions, so that the cutting edge C is always maintained in a V-shaped expanded shape.

Therefore, the scissors can be inserted smoothly into a sheet-like object M such as paper, cloth, or synthetic resin film, and the two halves 2 can be closed while resisting the springiness of the metal plate A. Therefore, the object M can be cut by rubbing the cutting edges C against each other.

P indicates the opening/closing fulcrum position of both halves 2.

When bending the metal plate A into a ■-shaped expanded shape in opposite directions, both halves 2 may be bent while remaining in the flat state, but preferably, they should face each other as is clear from Fig. 6. It is bent as a convex curved shape.

Then, the cut edge of both halves 2 is set as the cutting edge C,
When cutting by the sliding action, the convex curved shape of the plate surface effectively holds down the sheet-like object M, and can reliably cut the object M without causing the cutting edge C to escape. Because it will be.

Furthermore, B is an opening/closing lever for both halves 2 of the metal plate A, and a mounting piece 6 is fixed to each half 2 along the cut edge that becomes the cutting edge C, and the plate surface of the other half 2 facing from now on. It is preferably integrally molded from synthetic resin and has a rectangular cross-section consisting of a blade section 7 that extends horizontally as if it is covered, and the pair of levers B close the two halves 2 at the time of the above-mentioned closing operation. In other words, they are sandwiched together and interlocked.

In other words, the blade edges C that are sliding against each other are exposed to the lever B from opposite directions.
During the cutting operation, the two halves 2 slide together and exceed the instantaneous overall flat state until they hit the blade 7 of the other lever B, so to speak. They are designed to move and pass each other.

The amount of passing movement is indicated by the sign.

Therefore, if you want to use this function, move lever B to metal plate A.
It may be formed by continuously bending and raising each half 2 of the .

By applying color to the synthetic resin lever B,
It is good to give that sense of beauty.

Reference numeral 8 denotes a plurality of protrusions projecting from the mounting piece 6 of the lever B, which are positioned and inserted into the mounting hole 4 of the metal plate A.
Moreover, they are fixed and integrated with adhesive.

The surface on which the fingertip of the operator rests on lever B (top surface
) is an inclined surface that is not parallel to the surface of the metal plate A, and is preferably provided with anti-slip irregularities 9.

θ indicates the angle of the inclined surface.

In other words, by placing your fingertip on the inclined surface of lever B and pressing it, you can ensure that the blade edge C collides with the blade edge C (second direction).
It is designed to apply a closing operation force in the opposite direction (not perpendicular to the plate surface shown by arrow F in Fig. 7).

According to this, the cutting edges C do not separate from each other, and the object M can be reliably cut by the sharp ridge line of the cutting edge without being affected by changes in its thickness.

The fact that both halves 2 of the metal plate A are bent from the folding line 5 forming an acute angle β with the cut line 1 also has a synergistic effect with a distant relative of this effect.

As described above, according to the configuration of the present invention, since the spring metal plate A is used as the scissors body, it is possible to automatically and continuously punch and form the cut line 1, including the engraving of the cut line 1. is used as the cutting edge C as it is, and there is no need to perform special cutting edge processing or install a separate cutting edge.Coupled with this, the mass production effect can be expected to the maximum, and it is easy to use. They are extremely useful as mold scissors.

In particular, the cutting edge C is formed by a cut edge at an angle α that is not perpendicular to the surface of the metal plate A, and is given a sliding action by the operating lever B, and is divided by the cut line 1. Since the two halves 2 are bent in opposite directions from the folding line 5 that forms an acute angle β with the cutting line 1, the sharp ridgeline of the cut edge allows them to slide against each other without separating from each other, thereby forming the cutting edge. C allows the sheet-like object M to be reliably cut,
The required structure is also extremely simple as described above.

It can be operated easily and smoothly by anyone using the lever B, making use of the spring properties of the metal plate A, and is also highly portable and safe, so it can be said to be an extremely convenient device.
